| 摘 要： | 基于Reissner-Mindlin一阶剪切变形板理论，讨论在预加面内机械荷载和温度场作用下，非均匀双参数弹性地基上中厚矩形板在动荷载作用下的动力特性。用一组数学上完备的二元多项式作为位形函数，采用pb-2Rizt法求得四边自由中厚矩形板的动力响应，并讨论了初应力对板的动挠度和动弯矩的影响。

| Abstract: | Based on Reissner-Mindlin first order shear deformation plate theory,dynamic response of an initially stressed,moderately thick rectangular plate resting on a non-homogenous elastic foundation of Pasternak-type is presented.Initial stresses are induced by in-plane mechanical loads or temperature fields.A set of pb-2 eigenfunctions,which effectively satisfies various boundary conditions,is adopted and Rayleigh-Ritz method is employed to determine the deflections and bending moments of the plate.The effects p... |
